- Triazines are the widely used herbicides and they can be introduced into rivers or lakes. When a human body
is exposed to triazines, nausea, vomiting, dyspnea and nephritis can be induced. Therefore, the ability to detect
triazine by qualitative analysis is required. In this study, an analytical method for 10 triazines including
simazine, prometon, atrazine, propazine, terbuthylazine, simetryn, ametryn, prometryn, terbutryn and cyanazine
was investigated. Liquid-liquid extraction of the triazines from human urine and analysis of the compounds
using gas chromatograph-mass spectrometry (GC-MS) and liquid chromatograph-mass spectrometry/mass
spectrometry (LC-MS/MS) were conducted. In the case of urine samples, extraction recoveries of triazines
were within the range of 71.99-111.91%. The calibration curves showed a good linearity (R2 of 0.998-0.999)
and method detection limits of all the analytes were obtained in the range of 0.10-0.95 ng/mL by the signal
to noise method (S/N>3). Instrument detection limits of the LC-MS/MS were within the range of 0.01-0.25 pg.
